Application filedDecembrllS, 1925;5eria1 N 0;75,6Q,' and Great Britain January 3, 1925.

This invention relates bacco pipe.

The object to an" improved toof the present invention is to I provide apipe which may be readily cleanedby separation of the constituent parts thereof.

A further object of the invention is to provide a pipe with relatively few parts, the

parts being so constructed that they are easily held togetheronassembly.

A still further object is to provide'a pipe wherein the smoke ducts are small but the smoke entering the smokers mouth is cool and at the same time free from bits of to-j Fig. 3 is a section on the line A-B ofv I Fig.

Referring in detail to the drawings, the stem portion comprises two parts 1, 2, interconnected by a dovetail tongue and groove 4, 3, the groove 3 being located preferably in the upper member 1 and the tongue 11 is formed which acts 4 in the lower member 2. Formed indthe dovetail ton ue 4; is a duct 5 formin a as sage for the smoke. I r

At the bowl end of the stem the upper memberl is providedwith a large aperture (3 and the lower member 2' is provided with a threaded aperture 7 of smaller diameter. A removable bowl 8 is proi idedhaving a connecting member 9 the lower portion of which is threaded as at 10 to'engage the threaded recess 7Qin the lower member 2. The diameter of the upperportion of the connecting member 9 is preferably less than the diameter of the aperture 6 in the upper stem member 1 so that when the bowl is assembled on the stem an annular chamber as a cooling chamber. I

The hollow portion 12 of the *bowl 8 adapted to receivethe tobacco is located entirely above the stem members .1, 2, and is connected to the annular chamber 1-1 by a plurality of ducts 13, for example 3, the size I of theducts being comparatively small and connecting with the upper portion of the chamber 11. Owing to the provision of the duct" 5in the uppermost portion of the lower member 2 the same connects with the lower portion'of the annular chamber 11 .so

that a considerable cooling of the smoke will take placein the said chamber. A monthpiece 141 of any convenient form 1s provided and connected to the stem members 1, 2 for example by a sleeve 15.

It will beappreciated that by removal of the mouthpiece andbowl the members 1, 2, mayabe easily separated and cleaned together with the ducts 13 of the bowl. Further, each bowl is a complete unit and is preferably made to standard measurements so that thebowl'8 may be replaced by another bowl in the case of burning of the wood-or cracking of the same. Further, the provision of the cooling chamber 11 between stem in position against the lower portion 2. I

I declare that what I claim is the bowl and the stem prevents the access of 1 small tobacco parts or moisture into the bore 1. In a tobacco pipe the combination of a I stein divided longitudinally in a horizons tal planemto an upper stem member and a lowerstem member, means to connect said" members together with relative longitudinal sliding. irioveineiit, a removable bowl, and means mounted on said bowl and engaging only with said lower stem member to hold said members from relative sliding movement.

2. In a tobacco pipe the combination of an upper stem member provided with an aperture extending vertically therethrough, a lower stem member having a threaded recess in its upper face, a removable bowl and threaded means projecting from the lower face of said bowl adapted to pass through. said aperture and engage in said recess to hold said stem members from relative movement.

3. In a tobacco pipe the combination'of an upper stem member, a lower stem member, means to hold said members from relative vertical movement, a removable bowl, and means projecting from the lower faceof said bowl through said upper stem member and engaging with said lower stem member to zontal movement.

4. In a tobacco pipe the combination of an upper stem member having a bearing surface at one end or its upper face and an aperture extending downwardly from said face, it lower stem member hawing a thread:

' 'tensionto "leave a cooling chamber, and coned recess in its upper face and aremovuble bowl having a threaded extension pass ng through thc apcrture of Stlld upper member and engaging with said recess to draw said 7 upper and lower members into clamping contact.

per 'la'ce receiving said extension, an upper stem membcr having an aperture of diameter greater than the diameter of said extens on sa d aperture surroui'idmg said ex- ,necting conduits between said chamber and the interior of snid bowl;
